1. Add one or more attachments by clicking the Browse button next to the File boxes for each attachment. If you want to attach more than three files, click on the Add Another File link next to the Attach Files button; there is no limit to the number of attachments you can add.
2. When you have selected all files you wish to attach, click on the Attach Files button at the bottom of the page.
3. You will see the list of your attachments in the table below. Click the Done button at the bottom of the page to return to your invoice.
4. When you are finished attaching files to this invoice, click Next to go to the Preview & Submit screen (see How do I preview and submit my invoice?).
